Is there a way to clone form field values in jQuery or javascript?

冷暖自知 提交于 2019-11-26 22:48:18
jQuery has a clone() function that clones the actual form with no problem, but it doesn't preserve any values that have been entered into the form. Is there a way to get around this? Sample code would be much appreciated. ran into the same problem, simple solution: // touch all input values $('input:text').each(function() { $(this).attr('value', $(this).val()); }); var clones = $('input:text').clone(); the trick is that this will change the actual 'value' attribute in the DOM tree, otherwise the data you enter 'on-the-fly' only exists in the DOM 'state' Stemming from the notes, here's a

Clone a file input element in Javascript

感情迁移 提交于 2019-11-26 22:40:38
I have a file input element that needs to be cloned after the user has browsed and selected a file to upload. I started by using obj.cloneNode() and everything worked fine, that is until I tried using it in IE. I've since tried using jQuery's clone method as follows: var tmp = jQuery('#categoryImageFileInput_'+id).clone(); var clone = tmp[0]; Works as expected in FireFox, but again not in IE. I'm stuck. Anyone have some suggestions? Editing the file form field is a security risk and thus is disabled on most browsers and should be disabled on firefox. It is not a good idea to rely on this

Is there any reason to prefer System.arraycopy() over clone()?

流过昼夜 提交于 2019-11-26 22:39:56
问题 When copying an entire array, I've often seen people write: int[] dest = new int[orig.length]; System.arraycopy(orig, 0, dest, 0, orig.length); But it seems to me there is no reason to favor this over: int[] dest = orig.clone(); They're both shallow copies anyway. Probably these folks just don't realize that clone exists. So is there any reason not to use clone ? 回答1: clone() makes a distinct copy of the first array with its own reference. System.arraycopy() uses JNI (Java Native Interface)

How to clone a Python generator object?

Consider this scenario: #!/usr/bin/env python # -*- coding: utf-8 -*- import os walk = os.walk('/home') for root, dirs, files in walk: for pathname in dirs+files: print os.path.join(root, pathname) for root, dirs, files in walk: for pathname in dirs+files: print os.path.join(root, pathname) I know that this example is kinda redundant, but you should consider that we need to use the same walk data more than once. I've a benchmark scenario and the use of same walk data is mandatory to get helpful results. I've tried walk2 = walk to clone and use in the second iteration, but it didn't worked. The

What is the difference between pull and clone in git?

问题 What is the difference between doing (after mkdir repo and cd repo ): git init git remote add origin git://github.com/cmcculloh/repo.git git fetch --all git pull origin master and git clone git://github.com/cmcculloh/repo.git I mean, obviously one is shorter, but other than that are they basically doing the same thing? 回答1: They're basically the same, except clone will setup additional remote tracking branches, not just master. Check out the man page: Clones a repository into a newly created

The character between git clone and http://... looks like a space, but it is a special Unicode character ! Short answer: After removing this character, and

Git doesn't clone all branches on subsequent clones?

别等时光非礼了梦想. 提交于 2019-11-26 21:23:05
问题 I have some problems with Git using cloned repositories and branches and it's somehow not possible for me to find an answer to this. Let me describe: we have a bare master Git repository here we all pull from and push to, located on a local linux machine and reachable with ssh. I made a clone of this to my usb thumb drive like this: git clone ssh://adahl@gollum//net/repos/netcube/patches.git This gives me of course a local clone with a working copy on my thumb drive. I cd to this and see some

ActiveRecord: How can I clone nested associations?

空扰寡人 提交于 2019-11-26 20:33:18
问题 I'm currently cloning a single-level association like this: class Survey < ActiveRecord::Base def duplicate new_template = self.clone new_template.questions << self.questions.collect { |question| question.clone } new_template.save end end So that clones the Survey then clones the Questions associated with that survey. Fine. That works quite well. But what I'm having trouble with is that each question has_many Answers . So Survey has_many Questions which has_many Answers . I can't figure out

What's the best signature for clone() in C++?

醉酒当歌 提交于 2019-11-26 20:14:31
问题 As Scott Myers wrote, you can take advantage of a relaxation in C++'s type-system to declare clone() to return a pointer to the actual type being declared: class Base { virtual Base* clone() const = 0; }; class Derived : public Base { virtual Derived* clone() const }; The compiler detects that clone() returns an pointer to the type of the object, and allows Derived to override it to return a pointer to derived. It would desirable to have clone() return a smart pointer that implies transfer of
